Hui light, battery Pooh

One first: The luminaire has a very good light output and a pleasant illumination. Previously I used a typical Cree China Bicycle lights with a single LED.
Opposite this light the Pleson is progress. Your lighting is clearly better.

BUT:
What good is the best light when the power source is on strike. It is NOT a 12,800 mAh battery case, but two batteries with 6,400 mAh supposedly. This could possibly still be alive.
But what did not work, the actual capacity of these batteries. After the lamp made suspiciously quickly limp, I loaded both batteries with a "real" charger from the RC section. The result after the third full charging: Battery 1 had 1,753 mAh battery and 2 even only 1,482 mAh.
That's not even a quarter of the declared capacity and causes the light at the highest level by holding half an hour.

Too Bad. So she goes the Pleson back.
